Many construction projects have used the building information modeling (BIM) extensively considering data interoperability throughout the projects' lifecycles. However, the current approach, which is to collect the data required to support facility maintenance system (FMS) has a significant shortcoming in that there are various individual pieces of information to represent the performance of the facility and the condition of each of the elements of the facility. Since a heterogeneous external database could be used to manage a construction project, all of the conditions related to the building cannot be included in an integrated BIM-based building model for data exchange. In this paper, we proposed an ontology-based facility maintenance information model to integrate multiple, related pieces of information on the construction project using industry foundation classesbased (IFC-based) BIM data. The proposed process will enable the engineers who are responsible for facility management to use a BIM-based model directly in the FMS-based work process without having to do additional data input. The proposed process can help ensure that the management of FMS information is more accurate and reliable.

The introduction of BIM technology is expanding not only in the field of design and construction, but also in the maintenance and use stage. In particular, researchers are looking to build a smart facility management system that integrates advanced IT technology and BIM. This study proposes the parts to be used and added to the BIM information, focusing on information generated and exchanged in the application case that is an issue during the current facility maintenance work by introducing the smart facility management technology and its use cases. The effectiveness of this proposal is compared with the scenario in which BIM-based facility safety management is applied and the current business scenario. In conclusion, the requirements for smart facility management are analyzed, and linkable parts between facility management tasks and BIM data that should be reflected in the facility management system are presented. In the maintenance phase, through the use case scenario, the facility management phase is subdivided according to the characteristics and contents of the work. In addition, information about the facilities required for each task is specified. Furthermore, it is examined whether BIM data and IT information can be linked with existing facility management systems. It is a process and guideline that can be provided to practitioners who want to introduce BIM and smart technology to facility management. It can define the required data items and levels according to the required information step by step based on the maintenance case.

The multi-mixed complex medical care facility consisting of mainly hospital and other associated facilities such as retail, office, accommodation, healthcare services, and so on, is currently recognized as a new segment in the real estate market. This study intends to identify the customer choice criteria for the development of multi-mixed complex medical care facility. Based on literature review and expert consultation, the 3 criteria with 12 sub-criteria for customer choice have been defined. And the AHP methodology has been implemented for the development of relative weight of those criteria depending on the type of facility including 'medical facility', 'supporting facility', 'healthcare service facility' and 'other ancillary facility'. Research findings indicated the implication for the optimal combination of facility development based on the customer choice criteria controlled by facility. Accordingly, this research intends to provide the guidance toward the development of multi-mixed complex medical care facility.

This research investigates the feasibility of Web technology as a means of delivering facility information for better support facility operation and maintenance. Our research proposes a Web-based feedback system as a pragmatic solution to the limitations of current FM (Facility Management) processes. In practice work orders and records are often misplaced resulting in lower efficiency and customer satisfaction. This may be overcome by a system that states information digitally and provides a Web-based interface. The interface could allow customers to report facility problems, trace their work order in progress, view schedules for maintenance and provide feedback for service online. The benefit for a FM department is that it can receive feedback on performance which would improve the quality of service and build a record of practical experiences.

Agent-based modeling (ABM), as a relatively new simulation technique, has recently gained in popularity in the civil engineering domain due to its uniquely advantageous features. Among many civil engineering applications, ABM has been applied to facility operation and management, such as energy consumption management, as well as the enhancement of maintenance and repair processes. The former studies used ABM to manage energy consumption through simulating human energy-related behaviors and their interactions with facilities, as well as electrical, heating, and cooling systems and appliances, while the latter used ABM to enhance maintenance process through facilitating coordination, negotiation, and decision making between facility managers, service providers, and repair workers. The present study aims to provide a short qualitative review on the most recent applications of ABM in the above-mentioned areas. Based on the review and follow-up analysis, the study identifies the advantages, disadvantages, and limitations of ABM applications to facility operation and management, and offers several potential future research topics in the hope of filling the existing literature gaps.

User-oriented Design is necessary in planning the interior design of Metropolitan Railroads trains, since this is a typical means of transportation in this modem society and all ages people with different body scale use this facility. However, there are little studies about facility panning and zoning of Metropolitan Railroads train considering users. Therefore, in this study, after completing the checklist based on the current legal standards of facility installation of South Korea and Japan, we examined user's facility and suggest several improvement of the opening 14 metropolitan railroad lines in Seoul. Then, we evaluated this facilities according to 41 standards; general facility(24 standards), safety facility(4 standards), guide facility(11 standards), other facility(4 standards). The result of this study may be summarized as follows. 1) General facility has to be designed to obtain lots of room for storage and this facility should be fixed up tightly with secure system. 2) Safety facility should be designed to minimize a difference of floor-level between threshold of train and ground. Also, using various color and material could help passengers to distinguish different space and facility. 3) Guide facility should be designed to guide passengers to the accurate direction with proper sign design in the pathway of Metropolitan railroad train. Also, more various color, which based on the research about physiological and psychological effect, should be used to guide people. 4) Other facility should equip more visual system using common good and informative contents. Through this study, we try to understand the current interior physical condition of Metropolitan Railroads trains. However, for future studies, it is expected to supplement evaluation standards considering aesthetic design, environmental improvement of indoor air quality and the satisfaction and demand of Metropolitan Railroads trains.

Recently, for the purpose of maintenance of facilities and energy, there have been growing cases of the 3D image scan-based reverse design technology mostly in the manufacturing field. In the MEP field, because of differences between design and physical model, the reverse technology has been utilized in factory facilities such as a semiconductor factory. Because 3D point clouds from scanning include accurate 3D object information, the efficiency of management works related to the complex MEP facilities can be enhanced. In this study, the reverse technology was surveyed, and the MEP facility management based on 3D image scanning was analyzed. Based on the results, a method of 3D image scan-based MEP facility management was proposed.

The purposes of this study were to assess the child care centers' foodservice facility, and to develop the kitchen facility model based on the general sanitation standards and guidelines in order to provide basic information for a plan review to build or renovate child care centers' foodservice facility. The scopes of the study include : 1) field assessment of the foodservice management practices and facilities in 8 public child care centers, and 2 private child care centers which they are subsidized from the government as public child care centers, 2) development of child care centers' kitchen facility model based on the General Sanitation Standards and Guidelines. The results of this study can be summarized as follows : 1. Field Assessment of the Child Care Centers' Foodservice Facility Average number of children in child care centers was 78.0$\pm$24.20, the average space of kitchen was 15.13$\pm$4.25($m^2$). Especially, the average space of kitchen was 18.49$\pm$4.35($m^2$) with enrollment capacity of 90～120 children in child care centers. The inventory level of most foods was relatively low except rice and kimchi. Kitchen facilities and equipments were similar to those of home kitchen and did not meet the standards of institutional practice. Therefore, the director in child care centers should recognize the importance of the sanitation management and pay more attention to the renovation of foodservice facilities as well as sanitation management practices. 2. Development of the Kitchen Facility Model based on the General Sanitation Standards and Guidelines The kitchen facility plan model with enrollment capacity of 100 children was developed based on the results of field assessment and literature review. Suggested kitchen space was 34.16$m^2$(6,100mm×5,600mm). This space was bigger than the results of field survey or precedent study, considered appropriate to implement the general sanitation standards. The main feature of the developed kitchen facility plan and model was product flow in one direction from the arrival of the raw material to the finished product in order to prevent cross contamination and to improve working efficiency.

We consider facility layout problems, where mn facility units are assigned into mn cells. These cells are arranged into a rectangular pattern with m rows and n columns. In order to solve this cell type facility layout problem, many approximation algorithms with improved local search methods were studied because it was quite difficult to find exact optimum of such problem in case of large size problem. In this paper, new algorithms based on Simulated Annealing (SA) method with two neighborhood generation methods are proposed. The new neighborhood generation method adopts the exchanging operation of facility units in accordance with adjacent preference. For evaluating the performance of the neighborhood generation method, three algorithms, previous SA algorithm with random 2-opt neighborhood generation method, the SA-based algorithm with the new neighborhood generation method (SA1) and the SA-based algorithm with probabilistic selection of random 2-opt and the new neighborhood generation method (SA2), are developed and compared by experiment of solving same example problem. In case of numeric examples with problem type 1 (the optimum layout is given), SA1 algorithm could find excellent layout than other algorithms. However, in case of problem type 2 (random-prepared and optimum-unknown problem), SA2 was excellent more than other algorithms.
